SAMUEL IIENSHALL LEA, OF NEW YORK, N. Y., ASSIGNOR OF ONE-HALF TO EDWINT. OG-LE, OF SAME PLACE.

TOOL FOR RESEATING FAUCETS.

SPECIFICATION forming part of Letters Fatent No. 571,572, dated November1'7, 1896.

Application filed August 19, 1896. Serial No. 603,236. (No model.)

To (@ZZ whom it may concern:

Be it known that I, SAMUEL HENSHALL LEA, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Tools for ReseatingFaucets; and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention has relation to improvements in expansion bits or cuttersfor reseating the valve-seats of faucets; and the object of my inventionis to provide an expansible or adjustable tool for truing up the wornvalveseats of the faucets used in dwellings on the hot and cold waterservice-pipes.

To this end the novelty consists in the construction, combination, andarrangement of the same, as will be hereinafter more fully described,and particularly pointed out in the claims.

In the accompanying drawings the same figures of reference indicate thesame parts of the invention.

Figure 1 is a perspective view of my improved bit or cutter in positionfor reseating the valve-seat of any ordinary faucet. Fig. 2 is a sideelevation of the bit. Fig. 3 is an end view of the same. Fig. 4 is atransverse section. Fig. 5 is a top plan view, and Fig. 6 is a top planview showing the bit adjusted to two different-sized valve-seats.

1 represents the shank, formed with a central transverse rib 2, and oneach side of this rib is a beveled shoulder 3.

4 4 represent the cutters, one being a duplicate 0f the other. The base5 of these outters is beveled, as shown, to correspond to the bevel ofthe shoulder 3 in which it rests.

6 is a longitudinal slot or recess in the cutters, which engage the bolt'7, passing through the central orifice 8 in the rib 2, one cutter beingheld in place by the head of the bolt and the opposite one by the nut onthe bolt.

Each cutter is formed with a cutting edge 9 and an integral stud or pinrounded, as shown, on their outer sides where they come in contact withthe orifice in the valve-seat, and which form guides for the cutterswhen at work.

In operation the nut on the bolt 7 is first loosened and the guide-pinsadjusted to correspond to the diameter of the orifice in the valve-seatto be recut. The nut-is thentightened, which firmly clamps the cutters4: at to the rib 2. In Fig. 6 I have shown in outline two differentadjustments of the cutters. The tool is then rotated steadily to theright until a sufficient amount of the metal is taken off of the face ofthe valve-seat to leave a perfect plane, which completes the operation.

The faucets may be recut without removing them from the pipes, and asthe cutters are adjustable faucets of various sizes may be recut withthe same tool without the necessity of employing a different-sized toolwhere the cutters are rigid, as is now the case. The cutters can bereadily removed for sharpening when necessary.

Although I have specifically described the construction and relativearrangement of the several elements of my invention, I do not desire tobe confined to the same, as such changes or modifications may be made asclearly fall within the scope of my invention Without departing from thespirit thereof.

Having thus fully described my invention, what I claim as new anduseful, and desire to secure byLetters Patent of the United States, 1s

1. A new article of manufacture, a bit for reseating faucets, comprisinga shank having a central rib, in combination with a pair of adjustablecutter-blades having guide-pins, and a retaining bolt for adjustablysecuring the blades to the shank, substan tially as shown and described.

2. A shank having beveled shoulders and a central rib formed with anorifice, a pair of adjustable cutter-blades having bolt-recesses andguide-pins, and a retaining-bolt passing through said orifice andrecesses, substantially as set forth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
